Hello, if there is a coil driver module separate from the distributor, the purple wire with white tracer should carry the rpm signal to the computer, there would be a pulse on that circuit, with the engine cranking. If the computer doesn't see the rpm signal, it won't ground the injectors. You can check B+ and ground at the injector plug.
